IMPROVEMENT IN CARPET-STRETCHERS.

Specification forming part of Letters Patent No. 138,333., datedApril 29, 1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that I, PETER KELLY, of the city, county, and State of New York, have invented a new and Improved Carpet and Oil- Cloth Vise, of which the following is a specification: V

In the accompanying drawing, Figure 1 rep.- resents a side elevation of my improved vise for laying and stretching carpets and oilcloths; and Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to furnish a strong and eifective vise for stretching heavy carpets and oil-cloths, which holds the same with a powerful gripe the stronger the strain exerted upon it; at the same time it works quickly and opens and shuts with ease. My invention consists of two jaw-levers, pivoted to two intermediate links, which connect .to the handle-lever, forming a powerful stretching instrument.

In the drawing, A represents the carpet, oilcloth, or other material to be stretched; B, the vise, ot-suitable metal, consisting of the jawlevers E and F'h'and handle-lever G. The jawlevers C and D are of S-shape, with sidewiseextending jaws a, and transverse teeth b, which lock in such a manner, one above the other, that a rigid and powerful hold of the material is obtained. The front part of the lever C is heavier and flatter, as lever D, being pronged from the jaw upward, and lever D pivoted between the prongs d by screw and nut c. The lower end of lever D is also straight, which, in connection with the lower part of lever (3, allows the vise to be placed in an upright`- position on the floor. The U-shaped lever Eis pivoted by screw c1, between the prongs d of lever C, and the S-shaped lever F to the lower end of lever D and outer end of lever E by screws c2 and e3. The handle-lever Gr is also ,pronged, so that lever F may pass between the prongs, and pivoted to the inner end of the U-shaped lever E by screw and nut e4. The ring-shaped end f of handle-lever Gr is placed in the hook of the handle H, by means of which the vise is operated in the usual manner.

The forward and backward action of the handle-lever Gr opens or closes the jaws a. The greater the strain of the handle-lever and the intermediate links, the more powerful will be the gripe of the jaws. No breaking of the parts or releasing the carpet is possible by a sideward strain, as the locking of the jaws is so perfect that even a sheet of paper may be held between them firmly.

The diferent parts are strong and durable, and work neatly and easily into each other, forming a superiorvise.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The jaw-levers (l and D, in combination Y with the intermediate links E F and handlelever G, pivoted and connected, substantially as and for the purpose described.

PETER KELLY.
